text: Capillary flow porometry permits obtaining several parameters and information in one individual and fast measurement. In general, a measurement with the wet sample (impregnated with wetting liquid) is carried out first. It is normally known as the "wet run" and the representation of the gas flow vs. the applied pressure is the so-called "wet curve". After the wet run the measurement of the same sample in dry state is carried out in order to register and analogous "dry curve". 
  The half-dry curve is calculated and represented by dividing the flow values with respect to the applied pressure by 2 and it is also represented in the same graphic.
  From the representation of the three curves it is possible to identify relevant information about the sample: the maximum pore size (or first bubble point) is recorded when gas flow through the sample is detected (please see explanation about FBP above), the mean flow pore size corresponds to the pore size calculated at the pressure where the wet curve and the half dry curve meet (it corresponds at the pore size at which 50% of the total gas flow can be accounted), and the minimum pore size results from the pressure at which the wet and the dry curve meet (from this point onwards the flow will be the same because all the pores have been emptied).
  Apart from these individual pore sizes, the same CFP measurement permits the representation of the cumulative filter flow distribution vs the pore size, which provides information about the percentage of the cumulative total flow through the sample that goes through the pores of a larger size than a certain value. Another information that can be obtained from the measurements is the corrected differential filter flow, which shows the flow distribution per unit of change in size, i.e. the increase in flow rate per unit increase in pore diameter. It is also defined as pore size distribution.
